Definitions

  • the operating member 12 which is illustrated alone in FIGS. 2 and 3 and which is, for example, made of a synthetic or plastic material is generally formed as a sleeve 15 having an axial bore 16 to be received or mounted on the guide member 11 and a flange 17 which is adapted to bear the actuating member 13.
  • the flange 17 is also equipped with lugs 18 at diametrically opposed positions for attaching the control member by which it is controlled.
  • the bearing bosses are individually formed as discrete members at the axial extremities of the bore 16.
